It started with the strange howling at night. Then there was the rabbit, torn to shreds.
Everyone thinks Grady's new dog is responsible. After all, he looks just like a wolf. And he seems a little on the wild side.
But Grady knows his dog is just a regular old dog. And most dogs don't howl at the moon. Or disappear at midnight. Or change into terrifying creatures when the moon is full.
Or do they?
For ages 8 to 12.
